that it clears the surface of the vater,-e-ach' tube having its endsprovided wlth tapered portions forming compartments separate from thecompartment inclosed by the body of the tube and with a keel extendinghe full length thereof and tapered to a paint bow and stern. I

My invention also consists in arranging the propeller midway between thestern ends of the buoyant tubes and as the water between the tubes isnot disturbed by the passage thereof over the water the propeller isrotating in a solid body of water instead of the disturbed mass in boatsof ordinary construction where the propeller is under the stern of theboat.

Still another feature of my invention eonsists in placing the ruddernear the bow of the boat instead of under the stern so that it does notinterfere with the operation of the propeller and has a solid mass ofwater to operate in.

My invention will be described in detail hereinafter and illustrated inthe accompanying drawings in which- Figure 1 is a central longitudinalsectional view of my improved boat, Fig. 2, a rear. view, and Fig. 3, alongitudinal sectional view of one of the tubes.

In the drawings similar rcfcrcnce characters indicatecorresponding partsin all of the \iews.

'lhe buoyancy of my improved boat depends upon the air tight tubes 1spaced apart: and having their ends provided with points 2 with theirtop surface on the same Specification of Letters Patent.

4 indicates angular plates secured to the top of each tube 1. in pairsand spaced apart, and 5 the deck supporting beams secured between saidplates.

6 indicates the deck secured to beams 5.

The propeller 7 is secured to the rear end of shaft 8 and driven bymotor 9 located on deck 6 forward of midship, the rear end of the shaftbeing journal-led in a box 10 supported by brackets 11 secured to theunderside of the deck.

The rudder 12 is, as shown, located near the head end of the vessel, therudder post 13 extending through the deck 6 and having its upper andsupported by a stand ard 14. I

The body of each tube 1 is constructed in a single air tight compartment15 and an air-pinup H3 is provided and connected by means of tubes or)ipes 17 with the compartments 15, 18in icating a pressure gageconnected with each compartment 15 to indicate the air pressure therein.The points 2 have compartments 19 therein separate from compartments 15and containing air under ordinary atmospheric pressure.

By locating the rudder near the bow end of the boat an advantage issecured in that the rudder plays in a Solid mass of Water undisturbed bythe bulk of the boat and by being to the rear of the forward ends ofpoints 2 it is protected from injury by striking obstructions.

The propeller, being located between tubes '1, has a solid mass of waterto operate in as the water between the tubes is not dislnrbcd andfurthermore the suction of the propeller is avoided so that instead ofthe boat going up hill at all times while in motion under the influenceof the propeller, the boat proceeds on even keel and its draft beingvery slight skims over the surface of the water at a high speedcomparable to the strength of he motor.
